Happy World Ocean Day!

Mark your calendars for June 8, 2025, as the world comes together to celebrate World Ocean Day. This annual event serves as a reminder of the critical importance of protecting our oceans and marine life.

Use our teaching and learning resources to show your class how sustainable fishing contributes to protecting our ocean for generations to come.

This World Ocean Day you can help protect the ocean

The ocean sustains our whole planet. It contributes to the air we breathe, the food we eat, the livelihoods of millions of people and so much more. And yet the health of our ocean is under threat from global warming and human activities such as overfishing.

World Ocean Day is our moment to show how sustainable fishing contributes to protecting our ocean.


Three things you can do to protect our ocean


  1. Inspire younger generations to learn more about the ocean and how they can protect it
  2. Promote ocean literacy in my classroom, finding ways to make the ocean relevant to the curriculum I teach and the materials I use
  3. Show younger generations how sustainable fishing helps protecting our ocean

Sustainable fishing means...

more fish

*16 million tonnes

Sustainable fishing allows fish stocks to replenish themselves naturally and balances the needs of the marine ecosystem for present and future generations.

more colour

*helps protect the beauty of the ocean 

By supporting the balance and variety of marine ecosystems, sustainable fishers help maintain the ocean’s resilience and its ability to recover from change and disturbance.

more choice

*20,000+ sustainable seafood products

Consumers can drive fisheries to improve their fishing operations through sustainable choices.

Watch these short films from ocean experts and scientists with your class, and use them as a starting point to explore the importance of protecting our ocean.

After watching, you can theme a lesson around the many advantages of caring for the ocean, from preserving biodiversity to supporting food security and sustainable livelihoods.

Here are some possible questions to spark debate and reflection in your classroom:

  • Why is it important to protect our ocean and the species that live in it?
  • What does sustainable fishing really mean — and why is it important for the ocean, people and the planet?
  • Why is biodiversity important for the health of the ocean? What could happen if we lose certain species?
  • What consequences can our food choices have for the ocean?

Build an Ocean Wall with your students

Dive into this activity with your students to co-create an Ocean Wall - a colourful collage of all the things the ocean gives us and the ways we can protect it. Through drawings, recycled materials and images, they will complete the sentence: "Sustainable Fishing means more..."

This activity will help your students to understand how sustainable fishing supports a more vibrant, abundant and healthy ocean, and to express their vision of what "more" could mean.

When your group's masterpiece is ready, share it with the world. Add your work of art to social media and tag us on Instagram and Facebook at @MSCecolabel or use the hashtag #MoreFish.
We'd love to celebrate your creativity!
